Traditional TRL calibration method assumes equal reflection at both reflection calibrators. However, process variation during circuit fabrication may result in unequal reflection calibrators. Correction equations are proposed under symmetrical transitions situation. More stable scattering parameters are obtained for single transition using proposed equations. Close results are also obtained for combined characterized transitions using correction equations and directly measured transitions.

“…In that case, several calibration/de-embedding methods, including those based on the single-mode S-parameter theory [13]- [18], can reach the goal of error correction. However, if the coupling cannot be ignored, which usually happens in practical highspeed differential pairs, the techniques [4]- [12] based on the multimode S-parameter theory [1], [4] are more desirable.…”

The multimode thru-reflect-line (TRL) calibration technique is widely applied to characterizing differential discontinuities. However, its accuracy is highly dependent on the inhomogeneity degree of differential transmission lines. In particular, in the case that the calibration structures are immersed in a homogeneous medium where different modes travel with the same propagation constant, the conventional multimode TRL is no longer applicable. To overcome this limitation, a new symmetrical reflect standard with distinct pure-mode reflection coefficients is proposed, and the conventional multimode TRL method is improved based on the assumptions applied to the reflect standard. A group of strip-line calibration kits are tested, and the proposed method is implemented to calculate the deembedded S-parameters of a symmetrical device-under-test. The experimental results show that, from 20 MHz to 16 GHz, the calibrated pure-mode parameters agree well with the simulation, and the cross-mode parameters are mostly lower than −30 dB. Moreover, using the proposed method, the average measurement error achieves at least 14.8-dB reduction relative to that before calibration, and a maximum improvement of 21.2 dB compared with that of the conventional multimode TRL.

“…The model of the combination of SMP connector and trace has been obtained by means of the thru-reflect-load (TRL) calibration technique in [5] by using a special tool made available by Agilent within Advanced Design System (ADS). For the probe model, the reciprocal-short-open-load (RSOL) calibration technique proposed in [6] has been implemented in Matlab.…”

In previous works forward wave analysis (FWA) was proposed for the EMC design of printed circuit board (PCB) power supply planes. In particular, FWA focuses on the radiation from PCB edges due to simultaneous switching noise on the power supply planes above 1 GHz and helps selecting the stitching ground via location by fast estimating their effect on the radiation. In the present work FWA is confirmed by experimental results up to 10 GHz based on the assumption that the maximum radiated field is approximately proportional to the mean edge voltage between top and bottom planes of the PCB.
